Via Videogum, we bring you a sneak preview of Jon Hamm's "multi-episode arc" on 30 Rock, playing Liz Lemon's ice-cream-making, frosting-smeared pediatrician neighbor and crush object. (He debuts the episode after next.)

Hamm's dreamy and everything, but we'd like to know a little bit more about this Oswald character—the one from the basement, with access to all the building's nails. Possible Jenna love interest? We'll have to stay tuned and see!
